As new Solaris releases become available, some library interfaces might
change their behavior or disappear entirely. Applications that rely on those
interfaces would then stop functioning. The Solaris Application Binary Interface
(ABI) defines runtime library interfaces that are safe and stable for application
use. Applications that are written to conform with the Solaris ABI will remain
stable under future releases of Solaris. The
appcert utility is designed to help
developers verify an application's compliance with the Solaris ABI.
